The present invention is relating to a protective device which used in the combination of extension cord, especially to a protective device used in the combination of extension cord or relating electrical as well as communication wire or cable.
In modern world, people keep increasing the utility of electrical facility, computer, communicating instrument and control system. These electrical facility and system use a lot of versatile electrical wire, cable line, data transmission line etc. During the use, the line always is insufficient in length and need the extension cord to lengthen the distance of power supply and signal transmission.
The combination or connection of line connection or joint of conventional extension cord, always loose caused by the pulling the line by external force; furthermore, the position of connectors may be pressed or get wet by water and become dangerous.
To solve the above-mention problem, there are many different solution had been provided. As shown in
The purpose of the present invention is to provide a structure of solving the above-mentioned problem, by providing a protective device in every wire connector of the extension cord. That is, providing a male component in the joint of an electrical wire and a female component in the joint of another electrical wire. Thereby, after combination of both joints, the male component also combines with the female component to form a device having an inner protective space.
The second purpose of the present invention is to provide a preset component on line joint. Said component can be divided to a male component and a female component preset on the predetermined joints for backup use.
Furthermore, by the technology of the present invention, the male and female component can be the same structures and locked respectively.
Referring to
Connector A 30 is an end portion of the conductive wire 31 for combining connector B 40.
Connector B 40 is an end portion of the conductive wire 41 for combining connector A 30.
Connector A 30 and connector B 40 are convention joints and can be in different types which enable to transmit the electricity or signal after connection.
As shown on
As shown in
As shown in
As shown in
The above-mentioned male component 10 and female component 20 are interchangeable. That means, the male component 10 is not limited to conform to connector A 30 nor female component 20 must conform to connector B 40.
The embodiments shown in
In the sum, the present invention is relating to the protective device of extension cord. By conform the type of connector, after the connection of connectors, enable the locking of the male component and female component. By the way, to form the protection in the position connectors combined.
Furthermore, said male component 10 and female component 20 can be designed in the same structure and can be locked respectively by each other. The purpose is to provide a protective space after interlocking, and said space can receive the wire and the combined of wires.
